The Marcellus Shale, Explained
Marcellus Shale is a sedimentary rock buried thousands of feet beneath the earth’s surface.
It stretches from upstate New York south through Pennsylvania to West Virginia and west to parts of Ohio. Named after a town in upstate New York, the rock itself is millions of years old, formed from mud and organic material.
The natural gas created over millions of years as a byproduct of decomposition is trapped in tiny spaces and fissures within the rock. The Marcellus Shale is just one of many shale formations across the world.
When industry speaks of tapping shale gas, it often refers to it as a “shale play.” The Marcellus is one of the first shale plays to be tapped, after the Barnett Shale formation in Texas.
But how do you know who’s drilling where? StateImpact’s interactive app answers that question, by tracking every single Marcellus Shale well in Pennsylvania. The app tells you who owns each well, what violations drillers have been cited for, and allows you to read articles we’ve published about drilling near the site’s location.
The interactive map allows users to search for wells by company or location, and includes a separate map devoted to tracking what violations are happening where.
Each well has its own specific URL you can link to or share via Twitter and Facebook. If you think there’s more we need to know about the drilling site, there’s a space for you to share comments, stories or pictures.
Our app is based on data from DEP’s website. The department updates production information twice a year, and refreshes violation reports about once a month. Data covering the first six months of 2012 became available in mid-August; the next update will come in February.
Some context on the app’s information: StateImpact Pennsylvania initially only tracked wells that were actively producing gas. In June 2012, we updated the app to display every drilled well. That gives a more accurate portrayal of drilling activity.
Despite Scotland’s fracking ban, imported American shale gas is key to the economy in one town. To some, it’s an uneasy state of affairs
One man who grew up near a major petrochemical plant thinks it’s a devil’s bargain: “Why should a community in America have to suffer what we’ve fought hard against?”
He touted his administrations deregulation as key to American economic growth.
Shale gas off-ramp: Pa.’s fracking boom produces a glut of ethane that’s helping fuel plastics production overseas
The path of a global supply chain often begins on land in western Pennsylvania and winds up half a world away, as the plastics industry increasingly relies on dirt-cheap American shale gas to feed its chemical plants and the globe’s growing hunger for plastics.
In Scotland, a town evolved with its refinery. Shale gas arrived to help the plant, but the town could benefit more, one resident says
Dispatches from Scotland, part 4: Grangemouth’s economy leans on the refinery there, and a business owner said she’s learned to accept living near the plant. But, she said, the town ‘should be more vibrant.’
Dispatches from Scotland, part 3: StateImpact Pennsylvania’s Reid Frazier talks to a University of Strathclyde professor about how it’s hard to tell how much gas is in Britain’s shale, in part because fracking generally gets a thumbs-down there.
Dispatches from Scotland, part 2: StateImpact Pennsylvania’s Reid Frazier talks with Kevin Ross, who runs a company that focuses on plastics testing and recycling and says U.S. shale gas is driving important investment into the UK economy.
